Technical description

Deserialization of Untrusted Data vulnerability in Apache Camel PQC Component.

The camel-pqc component persists post-quantum key metadata (KeyMetadata) through pluggable KeyLifecycleManager implementations. AwsSecretsManagerKeyLifecycleManager.deserializeMetadata() reads that metadata back from the configured AWS Secrets Manager secret by Base64-decoding the stored value and deserializing it with a raw java.io.ObjectInputStream.readObject() and no ObjectInputFilter or class allow-list; the cast to KeyMetadata happens only after readObject() returns, so any readObject() side effects in a crafted object run before the type check. A principal who can write to the AWS Secrets Manager secret that holds this metadata (requiring secretsmanager:PutSecretValue on that secret) could store a crafted serialized object that is deserialized during normal key-lifecycle operations, potentially leading to code execution in the context of the application that manages the keys. This is the same underlyi
